-What it says on the tin.
If you wanted to move an aircraft by air in wartime before you took off you applied to the Movement Liaison Section for a Movement Serial Indicator and to tell them your route with approximate timings. The MLS gave you next available serial from a letter/number sequence and recorded your details on a list which was sent to all filter rooms.
When the aircraft was picked up on RDF/Radar/Observer Corps and reported as unknown to filter room the duty Movement Liaison Officer looked up his list for who was authorised to be there and said either "friendly MSI - disregard" or "hostile - engage".

Orb expertise needed. Can anyone tell me what the "X" numbers mean that are allocated to each aircraft and crew of this orb? Individual radio call signs perhaps?
